What causes mercury in a thermometer to rise?
The mercury in a thermometer rises because of thermal expansion. When the temperature surrounding the thermometer increases, the molecules of the mercury expand, causing it to move up the narrow tube of the thermometer.
Why does the mercury not fall or rise in a clinical thermometer when taken out of the mouth?
Mercury does not fall or rise in a clinical thermometer when taken out from the mouth because of the KINK present in it.
What happens to the mercury in a thermometer Why?
The mercury in a thermometer expands and contracts as temperature changes. This expansion and contraction causes the level of mercury in the thermometer to rise or fall, providing a visual indication of the temperature.
Why does the mercury in the thermometer go up when the temperature is high?
In a mercury thermometer, the mercury expands when it is heated, causing it to rise in the thermometer's narrow tube. This increase in volume is a physical property of mercury known as thermal expansion. The height of the mercury column in the thermometer is then used to measure the temperature.
The function of a Mercury thermometer?
A Mercury thermometer measures temperature by relying on the expansion and contraction of the liquid mercury inside the glass tube. As the temperature changes, the mercury expands or contracts, causing it to rise or fall in the tube, indicating the temperature.

What is the definition of Glass thermometer?
thermometer consisting of mercury contained in a bulb at the bottom of a graduated sealed glass capillary tube marked in degrees Celsius or Fahrenheit; mercury expands with a rise in temperature causing a thin thread of mercury to rise in the tube

How do you test the temperature of the air?
You can test the temperature of the air using a thermometer designed for measuring air temperature. Simply place the thermometer in the area where you want to measure the temperature and read the display. Be sure to avoid blocking the airflow around the thermometer for an accurate reading.
What will happen if you hold a mercury thermometer from its bulb?
If you hold a mercury thermometer from its bulb, the heat from your hand can cause the mercury to expand and rise in the tube, giving an inaccurate reading. Additionally, mercury is toxic, so it is not safe to handle a broken thermometer. Always handle thermometers by the plastic casing to avoid these issues.
Why does mercury level goes down for a very short time when a mercury-in glass thermometer is placed in hot water?
When a mercury-in-glass thermometer is placed in hot water, the mercury expands rapidly due to the increased temperature, causing the level to momentarily rise before dropping back down as the thermometer equilibrates with the new temperature. The initial rise is due to thermal expansion of the mercury, while the subsequent drop occurs as the system reaches thermal equilibrium.
What makes mercury go up and down a thermometer?
the heat and temperature that causes it to rise and fall.
What is the construction of mercury thermometer?
A typical mercury thermometer consists of a glass tube with a bulb at one end filled with mercury. As the temperature changes, the mercury expands or contracts, causing it to rise or fall in the tube. The temperature is then read based on the level of the mercury within the graduated scale on the tube.
Why the mercury can not rise in a lab thermometer if there is air in glass tube?
Because the pressure of air may be greater than the pressure of the ascending Mercury.
Why will the mercury in the thermometer rise after 3 minutes?
The mercury in the thermometer will rise after 3 minutes because it expands when exposed to heat. As the thermometer absorbs the heat of the environment, the mercury inside it will expand and move up the tube, indicating a higher temperature.
